Acromegaly secondary to growth hormone releasing hormone secretion.

BACKGROUND

Acromegaly secondary to growth hormone releasing hormone (GHRH) secretion is exceptionally rare.

AIM: To report a case of acromegaly diagnosed in 1984 and assumed to be pituitary in origin. Sixteen years later, the cause was found to be a GHRH secreting neuroendocrine pancreatic tumour.

METHOD: A case report.

CONCLUSION

Although ectopic GHRH production is very rare, endocrinologists should be aware of this possibility in acromegaly patients if a pituitary tumour was not detected using pituitary imaging.
